T 0 @ZZ fw lio/m, it may concern Be it known that l, MATTHEW T.V CHAP-MAN, a citizen of the United States, and a resident of Aurora, in thecounty of Kane and State ci' illinois, have invented certain new anduseful Improvements in Pumping Apparatus, of which the Jfollowing is aspecication, reference being had to the accompanying drawings.

This invention relates to mechanism designed primarily for use as ameans for irrigating lands lying adjacent to a body ci' water, as ariver, and from which body of water the land is separated by aprotecting structure, as a levee, or which may be alternatively employedto force back into the river or other body of water any water that hasoverflowed the land. While the pumping oi water for irrigating anddrainage purposes are the principal uses that l contemplate employingthe mechanism for, it is to be understood that the invention may beotherwise advantageously employed, as for example, under someconditions, in the pumping of large quantities oic sewage. The inventionwill, however, be herein described in connection with the pumping ofwater 'from overllowcd land to an adjacent body of water which will Jforconvenience be hereinafter referred to as a river, and the pumping ofwater upon the land for irrigating purposes.

The leading objects of the invention are to provide simple and effectivemechanism for accomplishing the above stated pumping opera-tions, whichmechanism can be readily installed upon an embankment or protectinglevee, and when so installed will be so positioned that in pumping wateroil' of the land the discharging end of the apparatus will be totallysubmerged in the river whereby a downward pull is producedk on the waterin the discharge pipe such as is produced by an ordinary pump whencreating a vacuum, thus causing a siphoning etlect that results in asaving of power in operating the pumping elements: also, to provideimproved means for automatically preventing the ooding of the land by asiphoning action at times when the pumping mechanism is out of operationand the height of the water in the river is such as to cause such aresult if means were not taken to prevent it; and, also, to providemeans for affording, when desired, an unobstructed and unaided ilow orwater either Jrom the river to the land or vice versa through conduitspassing rnn AMERICAN WELL through the embankment or levee with whichconduits the inlet and outlet water passages that constitute apart ofthe apparatus will normally be in communication. @ther objects of theinvention are to provide improvements in various parts that enter intothe construction of the apparatus. The-se various objects l accomplishby the devices and combinations of devices illustrated in the drawingsand hereinafter particularly described. rlfhat which I believe to be newand desire to cover by this application is set forth inthe claims.

portion of such levee shown in the drawings isl preferably ofVconcrete-'or other` similar about to be described and the protectinghousing therefor. In such portion lof the Vlevee are formed two inclinedpassagewaysl of a size and shape to properly V'receive and hold asuction or inlet pipe and a discharge These pipes are .placed atVV ashort distance Vfrom each other at ,their upper ends VandVdiverge'downwardly toward the land and river, respectively, so thatwater may beforcedV through them and through a member that connectsthemnear their upper ends. In the drawings the suction'pipe re-' ferred tois indicated .by 16T.; the discharge pipe by 17 and the connection attheir upper endsfby 18.

As itis important vtormalre provision for withdrawing the suction pipe16 together with the pumping elements containedtherein I provide a tubein the pas;V sageway formed throughthe land'side part of the levee,which tube constitutes a coin-V parative'ly smooth lining for suchpassage way and affords means for providing suitable guides upon whichthe suction pipe v may be movedV longitudinallyV with comparative ease.

pipe.

Vbe employed, I have shown a `simple construction consisting of arail 2Oextending ,longitudinally of the suction pipe and riveted to theV outerface thereof, whichVV pro- Vjects into a traclrway inthe tube 19,-'suchtraclrway being constructed by leaving a Vspace between adjacentlongitudinal edges of twoV of the sheets'that form the tube 19 andbridging such space by a strip 2l which is Vriveted tol theouter facesVof such two sheets and over the joint between them (see Figs. 5, '6 and7 This construction will be duplicated near opposite sides of thesuction pipe and its inclosing tube, and by reason of the two rails 2Oprojecting between the separated sheets there willV be provided reliableguiding means for aiding in theinsertion or withdrawal of the suctionpipeV and which will also act to hold such suction pipe against rotarymovement.

In Fig. 10 l have Vshown a modification wherein the space between ltheseparated sheets of the tube 19 is bridgedbyV an out- Vat" theirabutting ends, and in so securing them l do it in the construction shownby means of annular channel `shapedqstripslEL Vthat overlie the jointsbetween such .tube sections and are riveted inV place, as shown inFiga-Sand 4,-the flanges of such chann nel shaped strips projecting.outwardly fand close to theinner face ofthe tube 19. Suchconstructionnotonly firmly unites the sev-V eral sections of lthe tubetogether, butby reason of the channel form effectually prevents the pipefrom becoming flattened or Secured to the' lower end of theV tube 19V isa funnel, indicated by 22, which has secured in it adjacent toits openlower end Va ystrainer 23 through which the'water passes yto be drawn upthrough the suctionV 2&1 indicates 'a rotatable pump shaftv extendingcentrally throughout Vthe suction pipe and having secured to it on itslower end portion prop ellers for drawing in .and forcing up thewatertobe pumped; The

Vlower portion of the shaft Vto which` the propelling devicesare-attached is preferablyV separately formed from the upper portion andofsoinewhat4 larger diameter than such; upper portion inV order that itmay be pro vided with a lubricant opening therethrough by which certainof the bearings may be lubricated, as hereinafter described. ThisVlowermost and enlarged portion of the shaft is indicated by 24a. It isshown as being secured to the main portion 24 (see Fig. 3) by means of aflanged coupling 24J riveted or otherwise secured to the shaft 24 andhaving its flange resting upon and bolted to a slightly enlarged headportion of the part 24,

25 indicates a member secured in the lower end of the outer tube 19 byany suit able means, such member being of wheel form-that is, itcomprises a rim, straight radial spokes and a hub. rIhe inner face ofthe rim portion is beveled as at 252L and the inner face of the hubportion is beveled as at25b (see Fig. 3) to make close fitting bearingsbetween such surfaces and correspondingly-shaped surfaces of the partscarried by the suction tube, thereby providing a tight lit between thelower ends of such pipe and tube. These `abutting surfaces arepreferably machined so as to insure accurate fits. The member justreferred to as being carried at the lower end of the suction pipe andhaving a close lit upon the wheel-like member25 is indicatedl by 26 andcomprises another wheel-like structure the rim of which is as shownextended up some little distance beyond the top surface of the spokemembers. The spoke members are preferably in the form of narrow bladesand lie opposite the spokes of the fixed part 25 so as to offer noobstruction to the passage of water rising between the spokes of themember 25. 27-2 -29 indicate other members arranged one above the otherand separated by a considerable spacefrom each other, all of suchdevices being substantially similar to and for the-same purpose as themember 26 except that the lower edge portions of their radial blade-likespokes are slightly turned laterallyV for the purpose of counteractingthe whirling movement of the water that is produced by the action of thepropelling means that forces the water up through them. 'Iheintermediate members 27 and 28 have their rim portions extending bothabove and below the upper and lower edges of the blades, and the uppermember 29 has its rimportion extending onlydownward, (see Fig. 3).lThese various rim portions abutl against each other as shown, and arepreferably iinterlocked as by a, rabbet joint as shown, and there areleft between these various stationary members 26-272829 considerablespaces in which are located the propellers hereinafter referred to.These stationary members are secured together by rods 30 passing downthrough them and screwed into the rim of the lowermost member as shown,or otherwise made fast to such rim, and said members are clampedtogether lby the screwing down of nuts 31 against the facek of therim'of the member 29. rIhe lower member 26 has an enlarged hub portion32, the lower end of the outer face of which is machined to form a truebeveled surface that accurately fits against the beveled hub of thesupporting member 25, and in the interior of this hub 32 are located aseries of anti-friction rollers 33 that bear against the lowerend of theshaft member 2da.` 34C indicates a plate covering the vopen lower end ofthe hub 32 and secured in place by bolts or otherwise. Preferably apacking member will be located against the inner face of such plate soas to more eifectually guard against 'the admission to the lower bearingof any of the water being pumped. The upper fixed member 29 is alsoprovided with an enlarged hub, indicated by 35, within which are a setof anti-friction rollers BGbearing against the shaft section 24a. 37indicates propeller wheels, the hubs of which are secured in anysuitable manner to the member 24a of the rotatable shaft.V I haveshownthree such propeller wheels each located between two of thestationary water-current controlling members, but it is to belunderstoodthat I do not confine myself to the number of such propellers andstationary members illustrated in the drawings. Each propeller wheel Iprefer to make of sheet metal and so twist the outer ends of the bladesthat the angle will be sharper on the inner end than it is on the outerend, thus making a perfect curve so that the distance through suchpropeller blades will be the same on the inner ends as it is on theouter ends of the blades. The blades will, therefore, be more flatontheir outer ends than on their inner ends and a helical curve will beproduced that will cause the water to iiow smoothly with the leastpossible resistance. The propeller wheels shown arefeach provided with arim connecting their outer ends and I so prefer to make them, and astronger device isthereby produced,` but I do not limit myself to theuse of a propeller with such a rim. Furthermore, the number of bladesmay vary `considerably from the number shown.

Inasmuch assediment may tend to collect in the annular space between thesuction pipe 16 and the tube 19 I preferably provide the rim of thelower fixed member 25V with openings extending therethrough andlcommunicating with such space, through which openings such sediment maybe discharged. As many of suchopenings may be provided as desired. Onesuch opening is shown in Fig. 3 and is indicated by 37a.

38 indicates a tube that* incloses and pro tects the rotatable shaft 24.As shown, it

is made in sections, the sections extending betweenvand being connectedto bearing boxes 39,'-such connecting of the tube sections `with theboxes being preferably by flanged collars V40 screwed uponr the ends ofthe'sections and bolted to the boxes. Within yeachbearing box arelocated lin the vconstruction shown a `series of anti-friction rollers41V that properly bear against the shaft, and each end of each bearing`box `isA to be tightly closed by cylindrical plates V.andV pieces offelt Yor other suitable material to exclude any ofv the water beingpumped from the interior thereof. f Each bearing box 3 9 has formed withit a series of radial arms 442rthree being preferably employed asshown-which extend yout and `abut against the inner face of the suctionpipe 16.

In lorder to hold the bearings perfectly stationary and centrally of thesuction ypipe V .I provide two of the arms 42 with endjprojections thatextend through suitable openings inthe pipe16 andenter the same spacesor'fjoints in lthe outer tube 19 as do the guiding Vrails 20'.V '(See-Fi-g. 5). By thisl arrangement suchprojecting ends of ltwo Y ofthe arms42 will also act as guidingde-v V vices in the samemanner as theVrails20. .Of

course, it will be understood that theV rails 2O must be made-insections with their ends spacedl apart suliiciently to allow of theprojection inthe manner stated of the :extensions/on the .arms 42. Theouter portions of these radial arms are broadened (seelig) topermit'the'passing therethrough ofrods or longsbolts. These irods orlong bolts connect the arms" of one bearing with'the correspondingfarmsofthe next bearing, and I prefer to arrange them with -rtwo of the threebolts-extending invone direction and Y the third bolt in the "oppositedirection, as

indicated in Fig. 4,-the two bolts that V extend in the same directionbeing the outer ones of the'series of three,`such arrangement insuringaneven draw or pull on the arms of the-bearings as a whole'.- Nuts fare Yshown screwed 'o n theendsof the'bolts tov hold them tightly in place.The .screw threaded' rods Vor bolts referred f to are `in-V dicatedby 43except those Vthat depend from theV lowermost/set of'arms 42 and thoseare designated, Vas -hereinbefore stated, b'y the numeral30 and serve tofirmly connect thev stationary water controlling `.members` 29- with:the lowermost setof arms 42-V 44 infdicatesfa cover plate extendingover V the upperend of the suction pipe 16 and inclosing .pipe 19 andbeing rboltedfsecurely, in the4 construction shown, to a portion of amachinery base` that `rests upon the con-v crete foundation 15, suchportion vof the base-` Vbeing indicated by 45 and shown as inclined f toconform to the inclination of the suction pipev and its inclosingv tube.VThe upper end of the shaft inclosing casing 38 is connected to theunder face of this plate 44, preferablyV byfmeans of a flanged Vcollar46 screwed to thecasing 38 and bolted to the plate.'V

plate 44 and'` preferably formed withVit.A 48

indicates a piston. fixedly. secured to theVV pump shaft 24. 'j Saidpiston ts the bore of the cylinder snugly, but not so tightlyas tointerferecwith therotation of the shaft. 49 indicates a cross wall nearthe upper end of the chamber in thecylinder 47 thus form# ing a secondand smaller chamberin which is mounted a mechanical bearingV comprisingan upper'and alower plate, icated by 50 and 51, respectively, and asetof anti-fric- Vmovable ina raceway formed in the faces of said'plates.yvThe lower plate `51 is Afixed in position While the upper plate 50 issecured to andturns withthe shaft 24.,VV The upper end' of the cylinderV47 is closed by a cover 'tion rollers52'interposed between them and V53 bolted to a flange of the cylinder andVv having .formed with it'fonemember Vof-a 'packing box 54 through which thepump 48 causing suchpistonto rise slightly "andthus in large measure relieve the mechanicalbearing at the upper end of the chamber 47 from the great 'load thatwould other'wise'be V imposed Yupon it, and thus to a large extentobviating the wearing of such mechanical bearing parts and preventingthe generation of heat that such wearing wouldf cause During the Vtimethat the liquidlubricant is thus vfed under pressurebelow the piston,such pistonlwill approximatelysupport the lengthwise pull of theshaftand its attached parts, but owing to the inclined position of the shaft:and the hea-'Vy' work that it is called upon -toY perform there is morethan theusual. `necessity. `for insuring a .proper lubrication ofA allofthe bearings of the shaft."

to obviatefthe. wear that would" otherwise occuron account of such`inclined position.

Suchr lubrication is afforded by the passage of Vtherlubricant underpressure from the cylinder 47'through the upper bearing and down thepipe' 38 that surrounds the shaft. Such lubricant-l will successivelypass through and keep filled Vthe several-,bearings afforded bythe boxes39 and upon leaving the lower; most one ofs'uch boxes it will followdown the shaft and enter a central opening V59 be returnedV tothatextendsfrom end to end yof the `shaftl section-.243, a portion of itbeing expelled throughy lateral passages O'that communi-` cate with thebearingmembers Y32 and35 Vthe water to so great an extent.

Lessines that inclose the roller bearings 33 and 36 respectively. By themeans described it will be seen, therefore, that not only does theliquid lubricating material that is forced under pressure beneath thepiston i8 slightly raise and largely support such piston and the shaftand its parts connected therewith, but also is so forced-above and belowthe piston as to keep properly lubricated every bearing for the shaft,and by its pressure prevents the liquid being pumped from entering thebearings.

The pump shaft is driven through the rotation of a shaft 61 havingsecured to it a bevel gear 62 that meshes with another bevel gear 68secured upon the upper end of the kpump shaft. The shaft 61 is supportedin bearings on standards l66 mounted upon horizontal portions of thebase l5 herein before referred to, such shaft being driven from anysuitable source of power through a pulley 64;, and an endless belt 65running thereover.

The passage 18 that connects the suction pipe 16 with the upper end ofthe discharge pipe 17 ll prefer to form in a flattened formthat is,considerably wider from side to side than it is from top to bottomA sothat the full discharge of water pumped up through the suction pipe 16will not have to be lifted as high as would be the case if such passagewere of uniform diameter and as large as the diameter of the pipes thatit connects. I thereby save power by not having to lift The dischargepassage 18 is shown as partly formed in the concrete foundation andpartly formed by a covering member 67, which latter forms a portion ofthe base upon which the driving means is mounted. Of course, if desired,such communicating passage 18 might be made wholly of a piece of pipeflattened so as to produce a passage such as described.

68 indicates a building erected upon the portion 15 of the levee orembankment over the operating machinery. f

TWhile the pumping apparatus herein. shown may be advantageously used byhaving the lower ends of the inlet and discharge pipes project beyondthe embankment or levee portion 15, l prefer to form in the lowerportion of such levee or embanlnnent two cross-channels indicated,respectively,

by 69 and 70, in which the water from the river and the water from thesubmerged land may freely flow, when certain gates hereinafter mentionedare opened,and with which the suction pipe and discharge piperespectively communicate, the effect being, of course, the same as ifsuch pipes were actually submerged in the water at the opposite sides ofthe levee. l prefer such gated channels, however, as it is sometimesdesir- -able to allow water to flow from one side to the other withoutthe intervention of any pumping operation, and further because by reasonof such channels and the arrangement of. gates with respect thereto I amable to i utilize my improvements, in the manner hereinafter described,for pumping water from the river to the land for irrigating purposes.

When water is being pumped off of the land, if the pumping devicesshould fail for any reason or the pumping operation be discontinuedthere would be danger, in the event that the water in the river shouldbe considerably higher than on the land side, that water from the riverwould be forcedV back, on the principle of a siphon, through the pipes17, 18 and 16 and thus render the work that had been done ofno avail,and, indeed, might result in even a greater over flowing of the landthan before any pumping had been done at all. 'lo 'avoid that happeningI provide means for automatically destroying the partial vacuum inthepipes that would permit such siphoning operation. Referring now to suchmeans, 71 indicates a small dome whose open lower end surrounds anopening 72 -in thebase or wall 67, such dome having a flange at itslower edge by means of which it is bolted` to such base member 67. Intheupper wall of the dome is an opening 73 that communicates with an elbow74C into which is secured a section Vof pipe 75. 76 indicates a valvepivoted at 77 to the wall of thedome and adapted when swung up to.lclose the open- 7 .-8, the face of the valvebeing, of course,

provided with a suitable surface for eifecting a tight closing ofsuch'opening. 78 indicates a lever pivoted at 79 to a bracket located onthenopposte side `of the dome from the point where the valve 76 ispivotally attached, `the free end ofsuch lever 78' lying beneath thevalve 76 and acting to close such valve when the lever 78 is swung up onits pivot. Substantially centrally of the` lever 78 is an openingthrough which loosel passes a stem 80 on the upper end of whica is ahead that rests against the upper edge of the lever. 81 is acomparatively longl arm that is pivotally attached at 82 'to a bracket83 projecting from the inner face of the dome near its open lower edgeand beneath the pivotal point of attachment of the lever 78. lPivotallyattached at 84 to this armV 81 is a short knuckle 85 that is alsopivotally attachedl to the lower end of the stem 8O that passes throughand depends from the lever 78. 86 indicates a coiled spring around suchrod and interposed between the lever 78 and knuckle 85, which, when thearm 81 is moved up, `acts againstv the lever -7 8 and causes it toforcibly bear against the valve 76 so that such valve will close theopening 78. Y

It is evident that with the pumping mec-h- Y. such valve to close the'vopening 73.

" force of the water being pumped will hold anism inoperation'theforcing of the outiowing water against the arm 81 will cause such .armto swing upward yon .itspivot 82, thereby forcing up the stem 80 whichmoves freely throughits opening inthe lever. 8,

but the effect of the coiled spring 86 ,willV b'e to force suchlever 7.8up tightly vagainst the under face of the valve 7 6, thus causlirlig iethese partsintheirraisedposition at all times during the. pumpingVoperation, but upon the stoppagefof such pumping opera.V

tiontheparts--will fall to substantially the position indicated inVFig.'2 and the valve 7 6.y will open' t'o a slight extent. Upon anyreverse movementof the water. through the pipes,V owing to the siphoningaction referred to, the arm 81 will berforced backso as to draw down theretaining lever 78l and thus allow the valve 76 tol opensufliciently toinsure 4a free communication between the interior of the .water passageand the atmosphere and thus effectually destroy the par- -tial vacuumthat would' make possible the'y siphoningaetionf While the backward flow`is -thus positively guarded against by vinsuring the wide .opening ofthe yvalve 76, such valve will, when the pumpis at rest, and

theupperiportion .of the lpipe system free from 4water, remain. normallyopen suflln cientlyso. that upon the commencement of a.

pumpingoperation the air in the pipes will I bedischarged in sufficientquantities through lthe discharge opening in the dome so that the.pumping action may proceed withouty interference-the valve being closedin the manner described by the effect'of the flowing water forcedthroughandrising'into the ltlattened communicating `passage 18.

`Itfis evident that through. the two' channels v691andy 70 water may beallowed to Vfreely .flow in eitherv Vdirection when the height ofthewater at either side ofthe levee jorembankmentawill.permit, but suchflow will. ordinarily be prevented. by gates moved It is desirable atVtimes, however, to draw water, from the .riverand discharge it underpressure upon :the land so as toinove it readily and rapidly acros'ssuchchannels.

at considerable distances from the levee and. embankment .for irrigatingpurposes, and to that end I have provided a series of gates Vacrossthesetwo channels by the manipula-V tion of which water from the rivermay be" admitted to the pumping mechanism only,

.and by such mechanism forced as described upon the land. vTheseV gates,inthe connumbered 89. and 90 are located, respec-V ystruction'shown,.comprise four in number, thatindicated by 87 being* adapted toclose the land side endof the channel 69,.an'd thatV indicatedby 88being adapted'to close the river side end of the channel 70, while thosetively, inthe .channels 69 and 70. Each'of the gates is movable to openand close it by any suitable-means-the means shown being a long rodconnected at its lower end to a gate and 'havingy its upperscrewfthreaded. end engaged by an operating iwheel, the.

turning offwhich, of coursefraises or lowers the rod as will beunderstood. In Fig. 1

these rods for the gates S7and 88 are shownV and are indicated by'91and92, respectively, and their respective. operating wheels are` indicatedby 93 and v9d. In order to perform the operation of pumping ,the riverwater onto the land for irrigating purposes, as above suggested, thegates 89 and 90 will be open. and, the gates 87 and 88 will be closed.It isi-evident that with such arf rangement ofthe gates water from theriver A.

Vwill pass through the channel G9 to the land end thereof, but cannotYpass out uponthe land, but will be acted upon by the pumping mechanismland drawn up through the suction pipe wand-connecting pipe 18 and 1 downthrough the discharge pipe 17 where it will be forced into the channel 70 and through such channel to the land lend there of, from-,whence itnia-y be conducted by ditches or otherwise to the places Von the landwhere A:irrigation is desired.

'By my invention I provide a rotary pumping mechanism of comparativelysimple construction that can be securely installed upon a foiuidationforming a permanent part ofV a river leveeor embankment and that wheninstalled can` be operatedto eliectively dis-V charge water eitherfroniithe land to the river or vice versa, and whichV mechanism is`onein that itmakes possible tliezremoval of the suction pipeyfromitsinclosing tube-:tof l gether with the operating elementsV containedinsuch suction pipe so as to permit of necessary replacements orrepairs.V To effect such removal the cover lffand the parts carriedthereby can be unbolted and removed after which thesuction pipe and itscontained parts can be drawn out lengthv wise from the tube 19, suchywithdrawal being rendered comparatively easy'by reasonA ofthe resting ofthe suction pipe onk its two rails QOthat'movein the guides formedas Ydescribed in the` outer inclosing tube 19.

In FiglQI havesliown a modified form.`

of construction wherein the principal change over the constructionalready described consists in substituting for the long suction` pipe 16a much shorter pipe or cylinder which is here indicated by 95. Such pipeor cylinder 95 performs the same functions as the pipe 16 of the otherconstruction with respect to supporting the fixed members that coperatewith the rotary propellers and it is made but little longer than isrequired to afford such support and inclose the propellers. As shown, itprojects some little distance higher up in the outer tube 19 than isrequired for such purpose and it is so made in order that the radialarms of the 1 lowermost bearing boX 39 may contact with and proj ectthrough the wall thereof so that the projecting portions may extend intothe longitudinal spaces or joints in the said outer tube for `guidingpurposes, as hereinbefore described in connection with the otherconstruction. In the firstdescribed construction only the two lowermostones of said radial arms had projecting ends that acted as guides, butin this modified form I have shown (see F ig. 13) all of such arms ofeach of the bearing boxes engaging in longitudinal spaces or joints inthe outer tube. The short tube or cylinder 95 is, of course,

to be understood as a suction pipe as that p term is used in thefollowing claims inasmuch as through it the water is first drawn, andwhile its upper end portion is not so directly connected with thenarrowed passage 18 that leads to the discharge pipe 17 as i-n thefirst-described construction yet of course it is so connected by reasonof the fiow of water from such shortened suction pipe through the tube19 to said passage 18, and hence it is to be understood that the claimscalling for the passage 18 connecting `the upper ends of the suction anddischarge pipes are to be construed as covering and applying to bothforms of the suction pipe shown. The modified construction is preferablein some situations to the construction that involves the longer pipeinasmuch as it involves less labor in withdrawing the apparatus owing toit being much less in weight. As all of the other parts are the same asin the other figures of the drawings they are indicated by the samereference characters as in those other figures.

Vhat I claim as my invention and desire to secure by Letters Patent, is-
